Something that came to my thoughts and i can't ever remember it being mentioned. In 2015 he signed for Southampton for a reported £10M - However, back in 2012 it was reported that when Chelsea took him from us, there was a confidentiality agreement in the 2007 transfer (KOL 4th May 2012), that prevented it being revealed a likely percentage sell-on fee. Does anyone know if we actually got anything and what percentage it was?
